I don't believe it, let Louis and Charlie in their run about two hours and only left them @ 9 o clock...just checking on them there is loads of blood on the blanket - checked both piggies, but no signs of wounds, I wondered if it was coming from one of their bums, and looking at Charlie you can see a bit of blood just in the inside of his bum...just reading on the net and on here, says it could be bladder stones or infection? - he is still eating fine and running around, but there is a lot of blood there all spattered around on the blanket. I'll try and get an appointment at the vets asap. I don't seem to be having much luck with my pets lately, hope he will be OK
